Effects of Hemoadsorption on Vascular Integrity in Septic Shock (ADSORP-VIP)

14 lipca 2026 zaktualizowane przez: Semmelweis University

Effects of Hemoadsorption on Vascular Integrity in Septic Shock (ADSORP-VIP Trial): Protocol of a Prospective, Randomised, Controlled Trial

This study aims to investigate the effects of adjunctive CytoSorb hemoadsorption therapy versus standard medical treatment on endothelial dysfunction in patients with refractory septic shock. The investigators hypothesize that hemoadsorption mitigates endothelial and glycocalyx injury by removing inflammatory mediators and other injurious circulating molecules, promoting hemodynamic stabilization.

Szczegółowy opis

This is a prospective, randomised, controlled, open-label, monocentric, proof-of-concept trial. Patients will be randomly assigned in a 1:1 ratio to receive either standard medical therapy alone or standard therapy plus continuous CytoSorb hemoadsorption for 24 hours. Blood samples will be collected at baseline, 6, 12, 18, and 24 hours, and then daily for 5 days to analyze endothelial markers, microRNAs, and inflammatory parameters. An adaptive group sequential design allows for an interim unblinded sample size re-estimation after the first 30 evaluable patients.

Changes in Syndecan-1 serum levels
Ramy czasowe: Baseline (T0), 6, 12, 18, and 24 hours, and then daily up to 5 days (including pre- and postadsorbent samples in the CytoSorb group)
Serum Syndecan-1, a marker of endothelial glycocalyx injury, will be measured in arterial blood samples. The outcome is the log-scale change from baseline to the T24 post-baseline Syndecan-1 value in ng/mL. If the T24 value is missing, the value will be considered missing. Negative values indicate a decrease from baseline. Syndecan-1 values will be analysed on the natural logarithmic scale due to expected right skew.
